基于飞行轨迹的捷联惯导系统算法仿真

根据载体在空间中的运动特点,利用工程软件Matlab对基于飞行轨迹的捷联惯导系统算法进行了仿真。先是通过建立基本运动模型模拟出载体的飞行轨迹,然后进行逆运算求出陀螺仪和加速度计的模拟输出量（角速度和比力）作为系统输入,并加入模拟噪声,最后通过合理的力学编排计算出运动载体的位置和速度信息,仿真结果验证了算法的正确性和系统的可行性。

Algorithm Simulation of Strapdown Inertial Navigation System Based on Flight Trajectory

According to the motion characteristics of carrier in the space, Matlab software is used in the algorithm sim- ulation of strapdown inertial navigation system based on flight trajectory. Firstly, the fight path of carrier is simulated by the establishment of basic motion model. Secondly, the analog output of gyroscope and accelerometer is computed based on the inverse operation, and the simulated noise is added. Lastly, the position and velocity is obtained through reasonable INS ar range equations. The simulation results verify the validity of the algorithm and the feasibility of the system.
